drm/amdgpu: Make enforce_isolation setting per GPU

2024-08-16T18:27:45Z

This commit makes enforce_isolation setting to be per GPU and per partition by adding the enforce_isolation array to the adev structure. The adev variable is set based on the global enforce_isolation module parameter during device initialization. In amdgpu_ids.c, the adev->enforce_isolation value for the current GPU is used to determine whether to enforce isolation between graphics and compute processes on that GPU. In amdgpu_ids.c, the adev->enforce_isolation value for the current GPU and partition is used to determine whether to enforce isolation between graphics and compute processes on that GPU and partition. This allows the enforce_isolation setting to be controlled individually for each GPU and each partition, which is useful in a system with multiple GPUs and partitions where different isolation settings might be desired for different GPUs and partitions. v2: fix loop in amdgpu_vmid_mgr_init() (Alex) Cc: Christian König Cc: Alex Deucher Signed-off-by: Srinivasan Shanmugam Signed-off-by: Alex Deucher Suggested-by: Christian König

Some chips have more than one gfxhub so check if we are a gfxhub rather than just gfxhub 0. Acked-by: Srinivasan Shanmugam Signed-off-by: Alex Deucher

drm/amdgpu: reject gang submit on reserved VMIDs

2024-07-08T20:50:53Z

A gang submit won't work if the VMID is reserved and we can't flush out VM changes from multiple engines at the same time. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Remove usage of the deprecated ida_simple_xx() API

2024-01-18T20:42:13Z

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So a -1 has been added when needed.

drm/amdgpu: rework reserved VMID handling

2022-12-14T14:48:33Z

Instead of reserving a VMID for a single process allow that many processes use the reserved ID. This allows for proper isolation between the processes. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
